1. A method of operating an audio device configured to be inserted in an ear canal, the method comprising:
- measuring sound pressure levels (SPLs) for at least one electrical drive signal directed to an ear canal receiver (ECR) during a time period Δ
t having a plurality of samples;
determining a SPL dose of the at least one electrical drive signal during the time period Δ
t using the measured sound pressure levels;
simultaneously estimating an ambient SPL dose within the ear canal during the time period Δ
t;
calculating a total SPL dose of the audio device using the SPL dose of the at least one electrical drive signal and the estimated ambient SPL dose; and
performing an action by the audio device when the total SPL dose is greater than a predetermined threshold.

Abstract
Methods of operating an audio device are provided. A method includes calculating estimated sound pressure levels (SPLs) for drive signals directed to an ear canal receiver (ECR) during a time increment Δt; calculating an estimated SPL_Dose during the time increment Δt using the estimated sound pressure levels; and calculating a total SPL_Dose at a time t of the audio device using the estimated SPL_Dose.
